Liliaceae, Chenopodiaceae, Lupinus, Potentilla, and Eriogonuni. His 

 more extensive single works are The Botany of California, published in 

 connection with Professor W. H. Brewer; and the Bibliographical 

 Index to North American Botany, a most valuable work, covering the 

 Polypetalous orders. 



After the death of Thomas P. James, and during the feeble 

 health of Lesquereux, Dr. Watson carried out successfully the 

 editing of their work on North American Mosses ; and two years 

 ago, with Professor John M, Coulter, he revised Gray's Manual of the 

 Botany of the United States, which had not been brought to date since 

 1867. By far the most important work Dr. Watson had undertaken 

 was the completion of the Synoptical Flora of North America, begun by 

 Dr. Gray. While he has not been spared to go far with this flora, 

 yet many of his contributions will be of the greatest assistance 

 in future work which may be done on the parts yet unpublished. 



In 1885 Dr. Watson was in Guatemala, where he contracted the 

 malarial fever of that climate, and since that time his constitution 

 had not gained its former strength. 



About the middle of December last he was attacked by the 

 prevailing influenza, which later affected the heart, and on March 9 

 he died at his home in Cambridge, at the age of sixty-five years. 



Dr. Watson was a man of high moral character as well as of 

 scholarly attainments. He was of a retiring disposition, preferring 

 the quiet of his study to social pleasures. His ability for continued 

 application was remarkable, yet he was always glad to stop his more 

 important work to give a word of advice or assistance to those whose 

 privilege it was to work under his direction.

WILLIAM BOWMAN. 

 Born July 20, 1816 — Died March 29, 1892. 



ONE of the most distinguished pioneers in the modern development 

 of Histology has just passed away in the person of Sir William 

 Bowman, Bart. Born at Nantwich in 1816, and having received 

 his early education at Birmingham, Bowman entered King's 

 College Hospital, London, in 1837, and two years afterwards became 

 Demonstrator of Anatomy in the Medical School. In 1840 he com- 

 menced surgical practice, and during the next decade all his leisure 

 was devoted to the investigation of the minute structure of the 

 mucous membranes of the alimentary tract, muscular fibres, the 

 kidneys, and other tissues at that time imperfectly known. The 

 more important results of these researches were published by the 

 Royal Society, of which Bowman became a Fellow in 1841, and
